Ultrasonic diagnostic analyzers

摘要

The invention relates to medical technology and in particular to a diagnostic apparatus using the ultrasonic frequency electrical signals. Useful model can be used in various medical facilities for examination of the heart and blood vessels near the surface states, determine the heart rate and the instantaneous velocity of blood flow in veins and arteries. The achieved technical result:; - expanding the frequency band of the generated ultrasonic oscillations;; - expansion state diagnostic possibilities of surface vessels, particularly assessment of the state of the veins and arteries of the upper and lower extremities;; - more efficient use of the analyzer in vascular surgery.; - providing input signal analyzer to a PC and increase ease of use;; Summary of the utility model is as follows: In the ultrasonic diagnostic analyzer based on the Doppler effect, comprising a housing (1), a power source (2), a sensor (3) in the form of two piezoelectric elements, the transmitter (4), the receiver (5), the signal processing unit (6), a digital display (7), a buzzer (8) and the control button (9), sensor input (3) connected to the output of the transmitter (4) and the output of the sensor (3) - to the input of the receiver (5), the source supply (2) connected to the transmitter (4), receiver (5) and a signal processing unit (6) and through the latter - with digital indicatrix rum (7). Transmitter Output (4) is connected to the input of the receiver (5), whose output is connected to the input of the processing unit; signal (6). power source (2), a signal processing unit (6), a buzzer and a digital indicator (7) arranged in the ultrasonic diagnostic analyzer body (1), which is connected via connector (10) with a replaceable unit (11) comprising a transmitter ( 4), the receiver (5) and the remote sensor (3) in the form of two pezoelementov connected cable (12) with the transmitter (4) and the receiver (5), wherein one connector part (10) is fixed in the ultrasonic diagnostic analyzer enclosure (1) and the other part of the connector (10) fixed in a removable unit (11). In this analyzer the housing further has a slot (13) for connecting a personal computer connected to the signal processing unit (6).
